TWINE-CUTTER.

Specification of Letters Patent. Pgfl qgnted N 30, 1915.

Application filed February 23, 1915. Serial No. 9,345.

To all whom it may concern:

Be it known that I, PHILLIP H. UNSIN- era, a citizen of the United States, and a resident of Fremont, in the county of Sam dusky and State of ()hio, have invented a certain new and useful Twine-Cutter; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to cutters for thread, cord, twine, rope, etc.

It particularly relates to devices which are commonly used for cutting thread. The device is conveniently located upon the hand of the user or it may be placed upon a suitably mounted rod or bracket or other supporting part located on a sewing machine. It is so made that the blade may be easily removed and replaced by other blades.

The invention may be used for a great variety of purposes, all of which come within the purview of my claims hereinafter appended.

To show the practicability of my invention I have selected one or two constructions embodying it. The constructions selected are illustrated in the accompanying drawings and are described hereinafter.

Figure l of the drawings is a perspective view of a thimble having the cutting device attached thereto. Fig. 2 is a similar view of the thimble shown in Fig. 1, showing the protector and guide for the cutter in an open position. Fig. 3 is a perspective view of the blade used in the device illustrated in Figs. 1 and 2. Fig. illustrates the device containing my invention as applied to a clip which may be slipped over a post or rod and may be used in connection with a sewing machine. Fig. 5 illustrates a further modification wherein the device is secured to a ring to which is attached a cross-bar and is particularly adapted to cutting heavy twine or rope. Fig. 6 is a top view of the device illustrated in Fig. 5.

1, Fig. 1, is a thimble, which may be applied to one of the fingers of the hand of.

the user. To one side of the thimble 1 is attached a blade holder 2. The blade holder 2 is formed of a strip of sheet metal, which is bent centrally, forming the sides 3 between which the blade 4 may be inserted and held 111 place. If desired, the upper and outer corners 5 of the sides 3 may be slightly bent inward in order to bend or extend about the bevel of the edgeof the blade 4L 0r pinch the blade and hold it in position in the holder 2. The nose thus formed also guides the materials to be cut to the edge of the blade. The lower end of the holder 2 is closed together and terminates in a knife blade joint 6. To the end 6 is hinged the channeled protector and guide 10 having the inwardly turned end 11 through which the pintle or rivet pivot pin 12 may be inserted, thereby hinging or pivotally connecting the guide and protector 10 to the holder 2 and to the thimble 1. WVhen closed, the sides of the channeled guide and protector are located on eachside of the blade and cover the edge of the blade 4 and prevent turning or dulling the edge and also prevents the operator from coming in contact with the edge and also presses the thread over the edge of the blade as the thread is drawn down in the cutting operation until the thread is severed. The freeor outer end of the guide and protector 10 terminates in a short curve 13 where the sides of the protector 10 are brought together. The curved portion forms a guide which directs the thread, cord, twineor rope to the upper end of the edge of the blade. The shoulder 1 formed by the curvature of the end of the guide 1O strikes against the sides of the holder 2 at a point slightly below the upper end of the blade L, while the curved end 13 extends outward beyond the edge of the blade and upward above the end of the edge of the blade. In cutting, the thread or rope or twine is easily caught by the rounded end of the guide 10 and in the movement ofthe thimble l with respect to the thread, twine or rope, the cord to be cut slides down into and within the curved end 13 of the guide 10 and along the edge of the blade 4 until thread, twine or rope is out. If need be, it will pass down the edge so as to press upon the edges of the sides of the channeled guide 10, which operates to push the thread, twine or rope against the edge until the thread, twine or rope is cut. The guide 10-may be held against free movement about the pivot pin 12 or it may be yieldingly held in position so that as the thread, twine or rope passes down the edge of the knife 4, the guide 10 will be gradually forced back or away from the sides of the holder 3, but in such a way as to hold the cord against the edge 4 until it is cut.

I have provided a spring 20, which is supported on the pin 12 and terminates beneath the knife blade joint 6 at one end 21 and into a hook 22, which hooks around the back of the channeled guide 10 at the other end. The channeled guide 10 is thus yieldingly held by the spring 20 against the holder 2 unless it is forced by the thread, twine or rope in the cutting operation, against the elasticity of the spring 20 away from the holder 2, while the thread, twine or rope is held against and being drawn down along the edge of the cutter 4: and until the thread, twine or rope is cut. In the form shown in Fig. 4, the cutter is attached to a clip 25 which .may be slipped over a rod or post or other suitable means of support.

In Fig. 5 is shown a form which is particularly adapted to cutting rope or heavy twine. Thedevice in Fig. 5 is provided with a sleeve 30 which may be inserted over one of the fingers of the hand, preferably the middle or third finger. At its lower edge it is provided with a cross-rod' l, which will lie across the lower ends or bases of the fingers within the palm of the hand when the sleeve is in position on one of the fingers. The holder 32 is secured to the back of the sleeve 30 so as to lie back of the finger when the sleeve 30 is in position. The upper outer corner of the channeled holder 32 is provided with inturned noses33, which grip the blade 4 so as to hold it in position as in the manner described in connection with the corners of the holder 2 of the form shown in Figs. 1, 2 and d. The lower end of the holder 32 is provided with abutting portions 34, which extend outward and toward the channeled guide 10 and so as to abut the sides of the guide 10 to hold the guide 10 in position with reference to the blade 4c and the edges of the sides 35 of the holder 32. The edges of the channeled guide 10 are thus held in spaced relation with respect to the edges of the sides 35 of the holder 32 above the portion 34. The holder 10 is yieldingly forced against the holder 32 by means of the spring 20 constructed substantially in the same manner as the spring used in connection with the device illustrated in Figs. 1 and 2. By this arrangement the material of the twine or rope will not be caught or bound between the holder 32 and the guide 10 in the cutting operation. The cross-bar 31 Copies of this patent may be obtained for forms a handle which gives opportunity for a hard pull in the cutting operation.

The construction selected and described may be greatly varied in the arrangement and manufacture of its parts and in the substitution of elements having equivalent functions, and such modifications may be used for many and various purposes and still contain the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is,-

1. The combination of a channeled holder, a knife blade within the holder, a channeled guide pivotally connected to the holder at one end and having a short curved portion, the knife edge located in the channel of the guide, a spring for yieldingly holding the guide in position with respect to the edge of the knife and the holder, the edges of the guide abutting against the edges of the holder.

2. The combination of a channeled holder, a knife blade within the holder, a channeled guide pivotally connected to the holder at one end, the knife edge located in the channel of the guide a spring for yieldingly holding the guide in position wtih respect to the edge of the knife and the holder, means for limiting the closing movement of the channeled guide, caused by the spring.

3. The combination of a channeled holder, a knife'blade within the channeled holder, a channeled guide pivotally connected to the holder, the edge of the knife being located in the channel of the guide, the holder having nosed corners extending over the upper end of the edge of the blade for guiding the material to the edge of the blade and hold ing the blade in position and a spring for yieldingly holding the guide in position with respect to the edge of the knife and the holder.

at. The combination of a holder, a knife located within the holder, a guide, means for yieldingly holding the guide in position with respect to the knife and the holder, a. cross bar a ring secured to the cross bar near the center of the cross bar, the holder and knife secured to the ring on the side opposite'the cross bar.

In testimony whereof, I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
